Energy is located on the sound head in which position?

Energy is located on the sound head in which position?

• A. Middle
• B. Edge
• C. Outer surface
• D. At random locations

Answer: (A)

In therapeutic ultrasound, the energy field emitted by the sound head is not uniform. The crystal vibrates most strongly at its center, producing the highest acoustic intensity there. As you move toward the edges, the beam spreads and the energy density decreases. So the energy is located primarily in the middle of the sound head. This is why treatments aim the center over the target area and use movement or overlap to distribute energy evenly. The edge, outer surface, or random locations do not describe where the energy concentrates.
